Title: Optical transmitter-receiver
Inventor: TSUKADA KAZUMASA
IPC: H04B10/556
Filed: 1987-02-17
Abstract: PURPOSE:To transmit/receive an optical signal with high quality by decreasing the time rate of the emission of a light emitting element to increase the light peak output and eliminating a low frequency zone having much invaded light component. CONSTITUTION:A pulse generating circuit 2 outputs a pulse C<+> having a pulse width t1 based on an input of a leading signal B<+> and a pulse generating circuit 3 outputs a pulse C<-> of a pulse width t2 (t1>t2) based on the trailing B<-> input. In this case, the pulse C<-> is a pulse having a pulse width t2 with a delay of t1-t2 with respect to the B<-> reference. The pulses C<+>, C<-> are synthesized and inputted to an electrooptical conversion circuit 5 as a transmission pulse D and converted into an optical pulse D'. Moreover, the time rate of pulse emission of the pulse D to the sent data A by selecting the minimum pulse width of the sent data as Tmin and selecting the relation of t1+t2<Tmin and the peak output of light is increased by the reduction of the time rate. Furthermore, the pulse D' is converted into an electric signal D'' by an optoelectric conversion circuit 6 and a low frequency component including much invaded light component is eliminated by a differentiation circuit 7.

Title: Dial pulse distortion correcting circuit
Inventor: SONE MASASHIGE
IPC: H03K5/04
Filed: 1978-03-20
Abstract: PURPOSE:To maintain a normal exchange operation by making a break time fixed. CONSTITUTION:When distorted dial pulses are applied to the input terminal, pulses which have a break ratio smaller than the input are obtained by break ratio elimination circuit 1. Meanwhile, since the output of monostable multivibrator 3 opens AND gate 2 normally, the output of break ratio elimination circuit 1 passes through AND circuit 2 and becomes the input of monostable multivibrator 3. Monostable multivibrator 3 is operated at the trailing edge of the dial pulse, and is restored to the original state after a fixed time. Consequently, the break time can be made fixed by operating monostable multivibrator 3 by the trailing edge of the dial pulse, and a stable break time can be obtained by monostable multivibrator 3 because AND gate 2 is closed.

IPC: G01D5/24
Filed: 1989-02-13
Abstract: PURPOSE:To achieve a larger electrostatic capacitance by inserting one electrode into a cylindrical dielectric body comprising ceramics or the like while another electrode is provided on the outer circumference of the dielectric body to make both the electrodes mobile relatively. CONSTITUTION:One electrode 12 formed in a rod is inserted slidably into a cylindrical dielectric body 11 made of ceramics. A metal plating is applied or a metal foil is provided on the outer circumference thereof to make another electrode 13 so that the dielectric body 11 and both the electrodes 12 and 13 compose a capacitor. When one electrode 12 is slid with respect to the dielectric body 11 with the electrode 13 negative and the other electrode 13 positive, opposed areas of both the electrodes change while an electrostatic capacitance varies according to the areas. Thus, by converting the electrostatic capacitance into a displacement, a displacement value of one electrode 12 can be detected.

Filed: 1992-02-20
Abstract: PURPOSE:To easily confirm the normal light emission of a light emitting diode(LED) by turning on the LED or making it flicker according to a display sequence which is previously set. CONSTITUTION:A three-color LED is used as the LED for displaying a power source 18e and controlled so as to turn on a green color in accordance with the turning-on of a power source when a photosensitive drum can be still used, to turn on an orange color in accordance with the turning-on of the power source when the life of the photosensitive drum is drawn to an end and to turn on a red color in accordance with the turning-on of the power source when the life of the photosensitive drum arrives at the end. Then, when a power source key 18a, a printing stop key 18c and a reset key 18d are simultaneously inputted under a state that the power source is turned off, the test processing of the LED is executed before a normal printing action is executed. That means when the LED 18e is turned on for a second, for example, switched so as to turn on the orange color and a second passes further, the LED 18e is switched so as to turn on a green color.

Title: Odor remover of diazo copying machines

Abstract: PURPOSE: To perform removal of odor and achieve the reduction in size of the copying machine by providing a changeover device to the driving device of a photosensitive paper conveying means thereby enabling the contact area of photosensitive paper and heater roller to be increased or decreased depending upon the kinds of photosensitive paper.  
     CONSTITUTION: The photosensitive paper having passed through the developing device is conveyed by an endless belt 15 at a speed V 0  in rhe arrow direction toward a heater roller 1. If here the photosensitive paper is intermediates and there is no need for applying a large volume of heat thereto, the peripheral speed V 1  of the heater roller 1 is made nearly equal to the conveying speed V 0  by the changeover device and therefore the intermediates assume the state shown by the broken line B, thus becoming substantially zero in the angle of winding to the heater roller 1. If the photosensitive paper is ordinary photosensitive paper, the peripheral speed V 1  of the heater roller 1 driven by the changeover device becomes larger than the conveying speed V 0  and the photosensitive paper is conveyed by being wound to the peripheral surface of the heater roller 1 by the pulling action of the two rollers 1, 9, whereby it is given with a large volume of heat.
